Both nails and screws are common in fence construction, including on pickets. Some builders prefer to use nails when connecting the pickets to the rails and screws when connecting the rails to the posts. However, the best option usually depends on the type of wood fencing and the variety of wood you choose.

If you come face-to-face with a wolf in your yard, chances are it will be afraid of you as a human. Make eye contact and get big—waving your arms to increase your size. Use noisemakers or air horns if you have them, or throw a few rocks around to discourage them from approaching you. If all else fails and the wolf does not retreat, back away slowly while maintaining eye contact and find safe ground, whether indoors or up a tree. 

The best fence option for you depends on your property, budget, and style preferences, but a corrugated metal fence could be a good option if you want something durable yet low-maintenance. Unlike wood, corrugated metal won’t fall prey to rot or pest damage, and the metal can be recycled after its life as a fence comes to an end.

A chain link fence typically lasts between 15 and 20 years, but with proper maintenance, it can last for 30 years or more. To preserve the fence, it's important to keep the mesh wire tight, which can be done with a come-along tool every 6 to 12 months. Investing in a fence with a galvanized, powder-coated, or vinyl-coated finish can increase its lifespan to 20 to 30 years and reduce maintenance needs, as these coatings provide extra protection against the elements.
